Canal Morphology

The complex root canal system of maxillary second premolars shows variations among different populations. The aim of this study was to evaluate the root canal morphology of second maxillary premolars in the romanian population. The number of roots, root canals and the root canal configuration were investigated using radiographs in both buccal-oral and mesio-distal incidence. They were categorized using Weine’s classifi cation. Among the 480 teeth, 90.83% had one root and 66.67% one root canal. The frequency of secondary maxillary premolars with two root canals (33.12%) shouldn’t be underestimated. Knowing the variations of the internal root canal morphology of maxillary second premolars in a certain population can lead the clinician to a better approach of the endodontic treatment.

Abstract Background The purpose of this study was to determine the anatomical variations of the root canal system of mandibular second molars using cone-beam computed tomography (CBCT). Methods 190 mandibular second molars cone-beam computed tomography images were reviewed. The evaluation was performed by a radiologist with endodontic experience and two endodontists trained with CBCT technology. Tooth position, number of root and root canals, C-shaped root canal system configuration, presence of extra root (radix), and radicular grooves were assessed. Data was statistically analyzed using The Chi-square test (α = 0,05) to determine any significant difference between gender and the total number of root and root canals, and any significant difference between gender and root canal anatomical variation. Results Overall, 85.5% showed two separated roots, 12.1% a single root, 2.6% three roots or radix. 87.7% showed three root canals, 12.1% two root canals, 2.6% four root canals, and 1.6% a single root canal. 10% showed a single foramen, 75.3% two foramina, 13.6% three foramina and 1% showed four foramina.19.5% showed C-shaped anatomical variation, 51.4% in male patients, 48.6% in female patients. According to Fan classification: C1 13.6% in cervical third, C2 10% in the middle third, C3 17.3% in middle third, 15.5% in apical third, and C4 12.7% in the apical third. Root canals number in these samples were 5.4% a single canal, 21.6% two canals, 70.3% three canals, and 2.7% four canals. The root showed 46% with one foramen, 46% two foramina, and 8% three foramina. Radicular grooves 83.3% were found in the lingual area and 16.2% towards the buccal area. Conclusions The most prevalent anatomic presentation of the evaluated sample was a mandibular second molars with two roots, three root canals, and two apical foramina. Their variation was C-shaped root canals and Radix Paramolaris.

Objetivo: Determinar mediante tomografía computarizada de haz cónico (CBCT), la prevalencia de segundos molares mandibulares que presentan sistema de conductos radiculares en C en la base de datos de un consultorio particular de especialidades odontoló-gicas de la ciudad de Cuenca en el período enero 2014 - diciem-bre 2016. Material y métodos: fueron evaluados 348 segundos molares mandibulares, se determinó la prevalencia de conducto radicular en forma de C de acuerdo con el sexo y a la localiza-ción. Resultados: la prevalencia de conducto radicular en forma de C en segundos molares mandibulares fue de 33,05%, esta prevalencia no cambió con respecto a la ubicación.De acuerdo con el sexo, la configuración en C fue más prevalente en mujeres (25,86%) que en varones (7,18%). Conclusiones: la prevalencia de segundos molares mandibulares con conducto radicular en forma de C es alta, fue mayor en el sexo femenino y no hubo variación con respecto a la ubicación. SUMMARYObjective: To determine through Cone Bean Computed Tomography (CBCT) the pre-valence of mandibular second molars that present a C-shaped root canal system in the database of a privatespecialtiesprac-tice dental office in the city of Cuenca in the period January 2014 - December 2016. Methods: 348 mandibular second molars were evaluated; the prevalence of C-sha-ped root canal was determined according to sex and location. Results: the prevalence of C-shaped root canal in mandibular second molars were 33.05%, this prevalence did not change with respect to location. According to sex, the C configuration was more preva-lent in women (25, 86%) than in men (7.18%). Conclusions: The prevalence of mandibular second molars with C-shaped root canal are high, was higher in the female sex and there was no variation with respect to the location.Keywords: Cone beam computed tomogra-phy, C-shaped canal, molar, root canal

Fracture of an endodontic instrument within the root canal system can occur due to incorrect use of instruments, and clinicians are confronted with a few removal options when considering this situation. The purpose of this article is to present the removal of a fractured endodontic file from the periapical region of the right upper central incisor, that caused a nasal floor perforation and otorhinolaryngological symptoms, with the aid of a dental operating microscope (DOM) and cone bean computed tomography (CBCT). Success was achieved when the fragment was visible and removed from the nasal fossa. The standardized techniques of removal or bypassing fracture file were not effective, and success was obtained with the aid of CBCT that made possible the visualization of the broken file inside the nasal fossa.
